To all whom t't may concern:

Be itknown that I, ARTHUR Barns, a

subject of the King of England, residin at Leicester, in the county of Leicester, 'ngland, have invented certain Improvements in Heel-Breasting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawing's indicating like parts in the several figures.

This invention relates to machines for breasting heels used in the manufacture of boots and shoes and has for its objects to improve the construction and arrangement of heel-breasting madhines and, more particularly, to provide a machineof this class which shall be capable of breasting heels more ra idly and which may be more easily 0 eratec than has been possible with mac ines prcviously-usedior this purpose.

With these and other objects in view, a feature of the present invention consists in the provision in a heel-breasting machine of Jower-actuated clamping members for I hol ing the heel to be breasted arranged to tion.

be controlled by the operator through the medium of arting mechanism for actuating a suita .e breasting device. The arrangement is preferably such that power is applied to close the clamping members before the machine can be started in order that the o crator may see that the heel is correctly (3 amped upon its support before the commencement of the breast-ing opera- It is considered to be within of this invention to employ any suitable power-actuated means for closing the clamp- 113g members before starting the machine to actuate the breast-ing device, as it is believed that. the present invention is the first to provide, in a heel-'breasting machine, a power-actua-ted heel clamping device the operation of which is controlled by the operator before the starting of the machine to nism for successively causing the operation of therpower-actuated clam ing members construction is such that said mechanism' and the starting of the mac inc, and the Qis relieved at the end of an initial movemeh'tfrom the stress of'controlling the clamping. numbers, so that the operator dis-v the scope s as ning vthe s ump lths tional force in the second operation aswould have had to be maintained but for the relief afforded by this construction.

Another feature of this invention consists in the provision of a breast gage for positioning the heel upon its support, which is arranged to be moved clear of the heel long tudlnally of the heel prior to the breast- 111g operation, and preferably this movement is automatically derived from c moving part of the machine; and the arrangement is such that the breast gage is automatically returned to its effective position after the breasting operation and in this last movement acts as a heel ejector to knock the breasted heel from its support into a chute which leads to a suitable recepi tacler' he present invention further includes the combination with an angularly adjustable work-supportin table provided with clamping members, 0 power-actuated mechanism for operating the clamping members constructed and arrangedto be controlled by the operator and to effect the clamping of the work in any position that may be given to the supporting table.

In the preferred embodiment of the inven tion, .a heel support is mounted for automatic movement to and from breasting 305ltion, in which it lies within the path 0 the breasting knife. The heel support comprises spaced clamping members and resilient means are provided to move relatively the said members into operative engagement with a heel positioned between them during an initial movement of the starting treadle. The heel is thus clamped in place before the machine is started so that the movement of the heel sup ort into the path of the breasting knife wi 1 not displace the said heel upon its support, which displacement woul be liable to occur if the 'heel were not clamped prior to the commencep The con struction is such that after the machine ment of the above movement.

has been started by a further movement'of the operating treadle, the heel moved a'utomaticall under the kni-fewhic support is is then autor'ziatical y actuated to breast the heel, and after this operation has en P iformed," thepheel support is moved from its heehbreasting fpos'itionnback to its heel-f8" ceiving position, and means aotuatedrby this i I v under' sheet the table. 'A' depending arm -36, pivdt'd to the table at 38, is provided last movement Of tllBillel support .-.are provided to open the clamping members against the resistance of the resilient meansand to hold them open until the'starting treadle, which in the meantime has been allowed to resume its original ated by the operator.

Other features of the invention will be hereinafter described and pointed out the claims.

In the drawings, Figure 1 is a side elevation of a preferred embodiment of the present' invention; Fig. .2 is an enlarged side; elevation of the upper partof the machine I shown in: Fig. 1; Fig. 3-'is a plan View of the heel sup ort'; Figs. 4' and 5 are enlarged detail view of a mechanism employed to control the actuation of the clamping members; and Fig. 6 is an'enlar'g'ed side elevation of an alternative construction of heel-breast ing machine.

Ad-

just-ing screws 14 projecting upwardlyjon each' side of the top off the ja'clr-post are provided to vary the angular positionof the the said'table. One of the-clamping'mmhers 26 is, as shown in 3, normally stationary and serves as a positioning device as well a clamping member and 'has a rearward extension 28 sl d ngly mounted fn the upper end of a Stem'BQwIiich u s"t ahly supported for, vertiea'l'movement in a socket in'the table.- Suitable meansinay be,

. It will be observed that the force for' tent 42 in the opening of the clamp, and

' ply the power to the lesser power nected by a bolt therefore the operator does'not have to sup actuate the clamp but only tion. Moreover, as the dog 54 passes clear of the tooth 52 at the end of an initial movement of the startin pedal, the operator is enabled to dispose 0% the stress of controlling the clamping of the work before commencing the starting of the machine and is thus relieved of exerting any such additional forcein the second operation as would have had to be maintained but for the relief alforded by this construction.

I Abreast gage 66 is employed in addition to the clamping members 26 and 34 to aid in initially heel upon the ta le 10 and is arranged to be moved clear of the heel and away from the path of the breasting knife when the jack- 3 post is moved into the position in which it is shown in Fig, 2 to bring the clamped heel under the breasting knife 2. The said breast gage 66 is, as shown in' Fig. 3, formed of two sections 68 and 70 which are conpassing through an openmg in one of the sections and a slot in the other section so that the age may be adjusted for dilferent sizes 0 heels. The sectlon 70 is provided at its upper edge wi' in Fig.

a heeLejecting projection 74 and the section 68 is mounted for limited pivotal movement at 75 upon a rod 76 which is supported for vertical adjustment in the arm 78 of a bell crank lever which is'pivot'ed upon the boss 24- on the jaok post and has its other arm 80 provided with a cam slot 82 arranged to slide upon the rock-shaft 4:6. The slot 82 is so shaped that when the ack-post is moved inwardly from the position in which it is shown in Fig. l'to the position shown 2 the arm 80 of the bell-crank lever' will be actuated to move the breast age 66" away from the jack-post leaving the heel free to. be operated upon by the breasting knife 2. The bell-crank lever supporting the breast gnge 'may be so shaped as to be ont -of the' why of the body of a boot or shoe when ihe machine is being used to breast a heel already attached to a, boot or sh sections so that the part carrying the breast gage can be turned down out ofthe way In bear upon the work and :to hold it down 1pm) the table during the breastin operanon, and comprises acjrod 84 s idmglv for controlling its actua ositioning and centering a holds the heel "and the jack-post moving out-ward the 1:10

or the arm 78 may be formed of hingedend adjustable tread clamp is employed' mounted in bearings 86 and 88 upon the head 4 and a compression spring surrounding the rod, having one end engaging the bearing 88 and the other enda boss upon the'said rod. The lower end of the rod 84 is preferably bent as shown in the drawings to provide sufficient surface to engage a heel and hold it firmly upon the supporting table.

In the operation of this machine, which will be assumed to be in the position in which it is stopped, as shown in Fig. 1, the

operator puts the heel to be breasted upon the pivoted table 10, which has been'adjusted by the screws l4, so as to enable the knife 2 to make its cut at the desired angle to the tread, and raises the breastgage 66 by swinging it about its pivot '75 and pushes the heel under the heel-ejecting projection 74 against the said gage 66 and ,the fixed clamping member 26 and then actuates the pedal which depresses the detent 42 and thus permits the spring 32 clamp and hold the heel in place in the manner hereinbefore' described. The further movement of the pedal actuates the clutch which starts the machine and the jack-post is then swung by the cam 16 and lever 18 to bring the heel beneath the knife while at' the same time the breast ga e is moved clear of the heel by the cam s 0t 82 in the;

arm 80 of the bell-crank lever, In the further operation of-the machine the knife 2 and tread. clamp 84 descend. and the latter upon its support while the former is breastmg it. The operation is completed by the knife head 4 bein y from the position in which it is shown in Fig. 2, to the position as shown in Fig. 1, when the detent 4C2 rengages the arm 36 as shown in Fig. 5 and, as before mentioned, opens the clamping device so as to release the breasted heel, and the projection 74 on the breast gage will, on the return of the latter to its effective position, engage and knock the breasted heel ofi the supporting table 10 so as to allow it to fall by way of a chute or defiector, not illustrated in the drawings, into a suitable receptacle.

In the modification illustrated in Fig; 6', the jack-post 92 gage 94 is mounted for movement upon a collar 96 ably su ported upon a lever 98pii'oted to guest at 100 and provided at its upper en with a roller 102 which'is kept in engagement with the face of a cam'104 carried'by theknife head 106 by means of a; tension spring 108 which is secured at one the main frame'ofi the machine; The cam so that the breast gag to close the raised is stationary and the, breast limited pivotal which is adjustto the said lever, 98 and at the other to 'is so shaped that its downward movement" swings the lever 98 away from thejack -post' moves clear at the :1 The lever 98 is 'ro'vi afihakatfe a the lattes de ce dsn s" pward" novement ot the, cam} permits" the spring to, return the ,ltWQL'. and the breast gage to theingoriginal relationcdnverse'l y, the
